PR1256 explicitly leaves later B cuts of PR1128's six width-seven helpers open. This scoped negative result checks all713 cuts /4278 helper-cut pairs of the fixed PR589 B chronology. The exact necessary-condition windows are helper465 after10–48 B records,468 after31–88, and470 after0–517. Helpers466,469 and476 never pass both the joint restoration/erasure-rank and first-restoration target-access tests.

The concrete new exclusion is helper466: its joint rank becomes8 after zero-based B[78], before its blocking target208 is read at B[88]. Waiting for that target read cannot rescue it in this fixed chronology. Passing a window is not a suffix construction, physical admission or new kappa. Lower-frame preparation, reordered target reads, changed prefixes and extra transport remain outside the model.

Only research/r439-later-retirement-cuts/ is added. The primary checker updates inverses incrementally; a separate checker rebuilds the entire inverse from scratch at every one of713 boundaries, with separate set-state and integer-geometry replay. They agree on every cut, donor set and lost-target set. Both import no predecessor executable code.

python3.12 scripts/research_package.py --package research/r439-later-retirement-cuts

Expected: PASS_LATER_BIT_CUTS pairs=4278, PASS_INDEPENDENT_LATER_CUTS full_inverse_rebuilds=713 helper_cut_pairs=4278, ten passing test groups, and PASS_REGISTERED_RESEARCH_PACKAGE. The registered Python3.12.13 replay passes; the census suite also passes under isolated optimized Python3.14.7. Controls cover six altered census claims, boundary indexing, donor/target support, missing coverage, source corruption, offline relocation and exact regeneration, plus the retained stationary fixture controls. Selected-record integrity and its five regression tests pass. Native/hosted supplier admission, the selected cold replay and remote CI are not claimed.

Exact base: dadfea6e8a78ff6ba901705f87532a71c6f5bbb8; OS seed17, user-assigned bit track. Ali Romman's PR1128 (df29b159239b79d7e451d6ddda826a73e0e50a67) supplies the boundary lemma and six candidates. Ross Richardson's concurrent PR1256 (d6d5a994fcdcd8d04ec439ff988daa8f37b17ece) supplies the first-restoration target-access implication and finite two-frame helper470 continuation. Its arrival subsumed our initial stationary experiment; that material is explicitly corroborative, and the single evidence-driven pivot is to its unsearched later-cut question. Exact source/document pins, bounded domain and next steps are recorded in the package. No selected or upstream/ files change.

100-PR batch review at 3437f884a0282af6acf51a1d9ef052c3e09e697b.

Merged to main, preserving the original contributor commits and package attribution.

Reviewed scope: Complete 713-cut, 4,278-pair audit of six retained helpers, including later admissible windows and an excluded late read. Independent inverse reconstruction and package tests pass; necessary windows are not completed hosting constructions.

The pinned scoped command passed; the batch ledger contains its command, input hashes, environment and log. This incorporates the research/tooling contribution and does not change the selected κ or discharge the inherited multiplication-theorem assumptions.

Batch review, attribution and evidence. Thank you for the contribution.
